Version information

Version 1.15.0•for Jira Data Center 8.0.0 - 11.3.7

Release date: Jul 2nd 2026
Summary: Improved migration reliability, performance, and error recovery
Details: Version 1.15.0 makes Jira migrations more reliable and easier to recover when problems occur. Large and clustered Jira Data Center instances now experience less rate-limiting during migration, with smarter retry behaviour for transient network errors during preflight and attachment uploads. Attachment migration is faster, and missing attachments are now clearly reported. Several bugs have been fixed: exports no longer fail on duplicate custom field rows, complex JQL filters with history clauses now migrate correctly, and Advanced Roadmaps team exports no longer produce broken imports. The remediation workflow is stronger — paused migrations resume more reliably, cross-project errors are correctly retried, and import-phase rich text validation catches errors earlier. Asset exports are faster with batch fetching and parallel processing. Scoped user migration now correctly collects all group references. Security hardening has been applied to file access paths.
